I just got results of my UOA back and there was unusually high aluminum reading, while all other metals were fine.
Latest UOA
I think high aluminum reading might be due to the way oil was sampled but just to make sure I would like to find out what is the 2 and 3 material bearing shell(shown in the image below) made from in this particular engine design?
Car is 2001 Audi S4 with 2.7L twin turbo V6 engine.
Would anyone know this or where could I find this info?
